Dr. Corina Tarnita describes the importance of termite mounds in a savanna ecosystem. Termite mounds are biological hotspots that concentrate nutrients. When viewed from above, the mounds form a strikingly regular polka-dot pattern. Dr. Tarnita uses mathematical modeling to explain the regularity of the pattern.
Figure 2.7 (OpenStax, Biology 2e) caption: Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration.

When the nerve cells of squid suffer an injury, something unexpected happens with the tiny pouches of colored pigment, called chromatophores. A MIT scientist discusses this phenomenon, and how it can be used and modeled on the computer with some surprisingly simple rules. Part of the "Science Out Loud" series.
The Center for Remote Sensing of Ice Sheets (CReSIS) is a Science and Technology Center established by the National Science Foundation (NSF) with the mission of developing new technologies and computer models to measure and predict the response of sea level change. CReSIS provides students and faculty with opportunities to pursue exciting research in a variety of disciplines; to collaborate with world-class scientists and engineers in the US and abroad; and to make meaningful contributions to the ongoing, urgent work of addressing the impact of climate change.

K-12 teachers attend a summer institute in physics education to learn the "guided inquiry" method of teaching physics. They learn inquiry skills by working through problems and experiments, questioning each other's rationales, and modeling the instructors' method of asking questions that "correct reasoning." The institute's purpose is not only to change the way physics is taught, but also to clarify teachers' understanding of basic physics principles.
With support from the National Science Foundation, aerospace engineer Michael Philen and his team at Virginia Tech are investigating the biomechanics of fish locomotion, in hopes of contributing to the next generation of robotic fish and underwater submersibles. They’re studying how fish use their muscles to swim efficiently and execute underwater maneuvers, such as darting around in perfectly synchronized schools. They’re also developing new smart materials, such as a bioengineered hair that is modeled after the hair cell sensors on the side of fish that allow it to detect minute changes in water flow.

Visionary oceanographer Scott Glenn leads a team of scientists as they race against time to launch the first autonomous underwater robot across the vast and dangerous Atlantic Ocean. Destined for Spain, the 8-foot bright yellow robot named RU27, or "Scarlet," is launched off the coast of New Jersey. Throughout her journey, data collected by Scarlet is fed into oceanographic navigation and forecasting models. Engulfed by the powerful ocean, our robot hero faces extreme weather conditions, ship traffic, and aggressive sea life that can terminate her mission. If Scarlet can successfully cross the vast Atlantic Ocean, her historic mission will inspire a future robotic oceanographic observation network critical for monitoring and predicting climate change.

A documentary film highlighting recent and past USGS (US Geological Survey) research in the Lake Tahoe Basin. It features USGS science activities conducted by hydrologists, geologists, geographers, computer modelers, and biologists. Some of USGS science detailed includes water quality monitoring, streamgaging, and use of aerial photography. The use of consistent, reliable, long-term data and maps are crucial for evaluating and maintaining the lake and basin.
Snakes certainly make it look easy when they slither forward, leaving perfect S-curve tracks behind them, but scientists have long been puzzled by the mechanics of their locomotion. Now, after a series of experiments and some computer modeling, David Hu has cracked the case. With funding from the National Science Foundation, he’s using math to determine how snakes slither and it turns out they move in a much different way than scientists have long thought.
From cleaning supplies to pharmaceuticals, surfactants are the compounds that make soap bubbly, paint spread smoothly, and medication dissolve more easily. Most surfactants are currently made from non-renewable petroleum sources and many of these surfactants don’t break down easily after they are discarded. Some can persist in the environment for decades. Their widespread use and environmental persistence has raised concerns about toxicity. At the University of Arizona, Jeanne Pemberton and her cross-disciplinary team work to create new “green” surfactants based on sugars that are generally known as glycolipids. With support from the National Science Foundation, Pemberton and her team are exploring the recent discovery of a versatile synthesis that allows production of many different types of glycolipids in large quantities. Some of these glycolipids are modeled after naturally occurring biosurfactants and some can be produced relatively inexpensively using renewable natural resources.
